iMPRovEMENT iN EYELETiNe-MAcHiNss.

Specification forming part of Letters Patent No. 64,761, dated Muy 14, 1867.

To all 101mm it may concern:

13e it known that I LUTHER HALL, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in EyeletingMachines; and I do hereby declare that the following is a full, clear, and exact. description of the construction and op eration ot' the saine, reference being had to the accompanying drawings, forming a part ot' this specification, in which- Figure l is a side elevation; Fig. 2, a front elevation; Fig. 3, a plan of the under side of the machine; Fin'. 4, a longitudinal central section of the eycletset; Fig. 5, a front or end view of the driving-shaft and the eccentricpiii, by nien-iis of which a lateral reciprocating motion is given to the punch and set; Fig. 6, atop view of the eyelet-hopper; Fi g. 7, a transverse section of the yelet conductor or chute; Fig. 8, a top view of the lower end of the chute; Fig. .i, a front elevation of the punch and set in the act of setting or heading down an eyelet, and Fig. 10 a front view of the eccentric und lever by means of which the required motions are given to the beds on which the holes are punched and the eyelets set.

Like parts are indicated by the same letters in all the drawings.

To enable others skilled in the art to make and use my invent-ion, I will new proceed to describe the construction and operation et' the Sil-IHC.

A is a metallic table or form, to the upper side of which is attached, by means of screws 1/ y, (see Fig. 3,) the hollow stud B, provided with the arni or continuation C, for the purposes hereinafterdescribed. D is a metallic box, the shape of which is shown in Figs. l and 2, constituting the carrier of the punch and set. '.llie top and bot-toni of the back of this carrier are provided with beveled 0r dovetniled coiitiiiinitions a. a', which slide on corierqiondingr wnys Il b', k being a gib, confined by set-screws I., as shown in Fig. 1. llie i'ront h ot" this carrier is removable, being confined b v incansol' screws -i j.

E is the punch, constructed like those in coninion use, with the exception of the top of the shaft., which (see dotted lines in Fig. 2) is a screw, and may be raised or lowered, as required, for the purpose of vertical adjustment. This punch, sliding in suit-able bearings in the top and bottom of the carrier I), is thrown np by means of a. spiral spring, g, the lower end of which rests on the inside of the lower plate of the carrier, and the upper end on a screwstud, f which is fast in the punch-shaft, and plays reely in the diagonal slot (see Fig. 2) in the front piece h.

F is the eyelet set or header, sliding freely in suitable bearings in the top and bottom of the carrier I), being raised by means of the spiral spring d, the top of which bears against the screw e, which is fast in the set-shaft, and plays freely in a slot (see Fig. 2) in the front It of the carrier. This set, as shown in Fig. 4, is hollow, and its top and bottoni are removable, tlie top being a screw which may be raised or lowered, so as to aiiord a vert-ical adjustment to the set.

a is a vertically-sliding steel pin, whose danieter should be a tritie larger than the sninllest inside diameter of the eyelets to be used. The top of this pin ais provided with an enlarged head, fn, which plays freely up and down in a chamber in 4the shaft, a'id limits thei-'ertical movement of the pin 1.. b is a round wire or pin moving freely in the bore of the set, its lower end resting on the hen-d of the pin a. These pins a and b are fortxid downward by means of a small s1 ira-l spring, d', the bottom of which rests on in enlargement of the pin b, and the top on the bottoni of the screw c.

G is the driving-shaft, which turns in suitable bearings in the stud B and front of the arm C, II being a flywheel, and I the handle by which the machine is driven.

Fast to the front cr' 4ne shaft G is a disk, J, provided with an e ientric-piii, M, (sce Fig. 5,) which enters anl plays freely in the S- sliaped slot (see dotted lines, Fig. 2) in the back of the carrier D, by means of which the requisite lateral movements are given to said carrier and its appendages.

K is a lever, which vibrates on the fulcrnm m in the top of the arm C. The back end of this lever is provided with a trietionroller n', runningr on the periphery of the double ram l., whieh is tast to the shalt. (l, and shaped as `shown in Figs. l and 2. r1`he t`ront oi' the lever is shaped as shown in Fig. 2, o being a raised step or continuation ot' the saune, und designed to strike on the top ot' the eyelet-hezuler F, as lu'reinat`ter described, p being an adjustable screw, by means of whieh the. pin (t (being acted upon thereby through the pin b) may be. forced a less or greater distance into an eyelet, as may be required.

N is a. pressure-foot', forced down by the spring t), b v means of'whieh the material to be c veleted is held upon the top ot the ta.- ble A.

lt is a strip ot' metal, the top ot' whieh is llush with thel top ot` the table A, in whieh it slides freely in a beveled groove. (See Fig. l.)

Fast t0 the under side ot' this slide It is a hollow stud, (represented by dotted lilies in Fig. 1,) through which and said slide plays up and down the steel pin S, on the top ot' whieh, as a bed, thev eyelets are set., there being a hole through the table to allow the requisite lateral motion to the said hollow stud.

T is a lever, the shape ot' which is clearly shown in Figs. 1 and Il, vibrating on the fuleruni-pin q in the shortbleek or cylinder U, whieh also turns with freedom en a vertical axis ot` its own.

V (see. Fig. 10) is a lever, the. upper end ot` which eneireles t-he et..eeutrie\vliee.l X, fast to the driving-shaft. G, inside. ot the hollow stud ll, h v means ot' which eccentric it is fiovious that. the lever V will be raised and lowered.

lhe lever Y is also provided with a slot, I', near its center, through whieh passes a t'ule.rnn1-pin,\\", (see. Figs. l and 10,) by means of whieh slot'. and pin it. is also obvious that a lateral motion will be communicated to the. lower portion ot' said lever.

'l`he lower eml ol' the lever is also provided with shoulders, (see Fig. 3,) which rest on the upper side ot' thc lever T, and a. head, which passes through the slot. m in said lever T, tbeing a. pin passed through said head, so as to hear on the. under side ot' the lever T, and thereby raise. the. same.

lhus itwill be seen that. the le\'c1"1,and eonseqnently the pin S, will have imparted to them both a vertical and a horizontal mo tion, and t'or purposes hereinafter described.

t), (see Fig. Il) is a slide similar to lt., ou the top ot' whieh the eyeletfholel is punched, the point where the. punch strikes being covertal with eopper or other material that, will notl dull the punch.

lhe contiguous ends ot' the slides Q, and R are. kept: together by means ot a spring, r, one eml ot' which is attached to 1t and the other to the screw n", projecting trom Q.

te is a serew passing through the lever T, as shown in Fig. so that its point shall strike against the end ot' the vibrating,r lever Y, b v

means ot' whieh screw the lateral movementl ot' the lever '.l, and eonseqlu-ntly the pin or bed S, may he increased or diminished, aeeording to the distant-.e required between the eyelet-holes.

The appara-tus by means otl which the eyelets are conducted to the. set or header F eonsists et` a hopper, B', agitator c', and ehute A', or their equivalents.

The hopper B', into which the eyelets to be used are ln'omiseuously thrown is a tlat-bot'- tomed cylindrical cup, of t-hin brass or other suitable material, supported on the upper end ot' the chute A', and at about the angle of inclination shown in Fig. 1. The lower side ot' this cup or hopper B' is provided with a series ot' holes,f', the. bases ot whieh are the bottom ot' t-he cup, said holes being,r of sueh a size and shape as'to just'. allow eyelets, when rest-ing on their flaring ends on the hopperbottom, to pass freely through them, and thence into the chute or conductor A'. The holes f' being thus arranged and shaped, it is impossible for an cycle-t. to pass through them unless it shall be presented right side 11p-1'. e., resting,r on its flaring end, and so as to enter the chute in theproper position to be inserted in the eyelet-holes.

Outside ot the cup B', and on the same plane with its bottom, is a tlnnge, o', (see. Fig. 6,) into whieh the eyelets pass immediately on leaving the holes j', and from whieh tlange they slide or drop into the elmte.

In order to constant-ly bring some one or more oi' the eyelets in the hopper into the proper position to enter some, one or more ot' the holes f', it is necessary that they should be continually agitated or kept in motion, which may obviously be done by many equivaient meelmnieal devices.

The drawings, Figs. 1 and 2, represent. this objeetJ as being accomplished by means ot' a rotating brush or arms, c', attached to the shatt. C', which passes through the center ol' the hopper, and into a step, 1)', on the top ot' the chute. This shat't; (.l' is rotated by means of a hand, d', passing,r from the shat't (.r over apulley, E', as shown in Fig. .1.

The chute. A is composed oi' thre. i strips ot` metal. as shown lin the transverse section, Fig. T-a broad top piece with two narrowerpieces attached by screws or otherwise to its under side., the contiguous edges ot the two nmler pieces being beveled, so as to reaeh over the flaring buse ot' the eyelets, a-nd' thereby keep then'. from dropping out.

One ot' these under pieces maybe adjusted laterally, it required, by means ot' the contining-serews r', which pass through oblong,l slots in the upper piece, whereby the eyeh'st-groove g' may be. aceonnnodnted to eyelets ot' diti'erent sizes.

In thel top piece of the chute, at the lower are somewhat less in diameter than the holes through which they pass, so that the chute, with its appendages, may have imparted to it a slight vibration or shaking every time an eyelet is picked out of the hole h by the set F, for the purpose of agitatin g the eyelets in the groove g', as well as in the hopper B', and thereby more cfi'ectually preventing them froinclogging. The upper end of the chute rests upon the pin t', as represented in Fig. l.

The operation of the machine is as follows: The eyelets to be set are poured promiscuously into the hopper B', and the machine turned until the chute A is full of eyelets. The article to be eyeleted is now placed in the required posit-ion under the presserN and punch E. The punch and set being in the relative position shown in Fig. 2, Sthe punch directly over tliepoint where the lio e is to be punched,

and the header directly over the lowest eye- A let in the hole ld.) the wheel H is now turned iu the direction of the arrow, and until one of the wings of the caiii-wlieel L has reached its highest point, by means of which, through tho action of lever K, the punch and set will be forced simultaneously downward, the punch through the material to be eyeleted, and the pin a. into the cyelct in the hole h', and thus a hole will be punched and an eyelet picked up, to bo in turn set into it. 'lhe wheel l-I is now turned farther, and the back end of the lever K descends the first cani, when the punch and header will be thrown up by the spiral springs d and g, and the carrier l), with its appendages, will he moved horizontally by the eccentric-piu M, Fig. 5, into the position shown in Fig. 9, while at the same time the pin or bed S will also be moved so as to be directly nuder the set F. The wheel H is now turned until the second enin of L has reached its highest point, which operation will have driven thc set down onto the pin S, which in the meantime luis risen up to meet it by the action of the eccentric X upon the lever T and the eyelet is inserted into the punched hole, and set or headed down, the pin a being forced upward out of the way, and the top of tliepin I; into a hole (shown by dotted lines in liig. 2) in the cud of the lever K. The wheel ll is now turned farther, and the back of the lever K descends the second cani of L, when the header lf` is thrown up by the spring d, and the carrier l), with its appendages, is moved horizontally by the ecceiitric-piii M in to the posit-ion shown in Fig. 2, while at the same time the pin or bed S nieves liorizontally, (the front end being still in the eyelet,) which will obviously carry or feed along the article to be eyeleted. The punch and set are now in the position first described, and ready to punch a new hole and pick up another eyelet.

Thus the whole operation of punching the holes, feeding the eyelets, picking tliem up and carrying them to the place of insertion, inserting and heading them down, and feeding along the material to be eyeleted, is perf formed with great rapidity and precision.

It is evident that the punch, instead of being a cuttingcylinder, may be made a solid rod, with a hole in the punching-table, over which the material is placed, and through which the punched-out piece falls.

The eyelets -may also be fed down and received upon the top ofthe setting-bed.
